Batch Reactors
A Gravity Displacement Autoclave is a reliable sterilization system that uses steam to displace the air inside the chamber through gravity. It is simple to operate and highly effective for sterilizing laboratory instruments, glassware, medical tools, and culture media.
In this method, steam enters the chamber and pushes the air out through a vent, allowing saturated steam to contact every surface for complete sterilization. Gravity autoclaves are widely used in hospitals, research laboratories, and small-scale industrial applications due to their ease of use, cost-effectiveness, and consistent performance.
Built with durable stainless steel and equipped with safety features like pressure controls and locking mechanisms, our gravity displacement autoclaves ensure safe, efficient, and contamination-free sterilization.

A Batch Reactor operates by charging raw materials into the vessel, where they undergo chemical reactions under controlled conditions. The reactor is equipped with an agitator system to ensure proper mixing and heat transfer. Steam coils or limpet coils are used to control heating and cooling, and sophisticated instrumentation ensures that reaction parameters are accurately monitored. The product is discharged at the conclusion of the process, and the reactor is cleaned in preparation for the subsequent cycle.
